PLUMBERS VISE.

SPECIFICATION forming part of Letters Patent N 0. 432,829, dated July 22, 1890. Application filed November 4, 1889. Serial No. 329,107. (No modeL) To all whom it may concern:

Be it known that I, JOHN HIRST, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certain Improvements in Plumbers Vises, of which the following is a specification.

My invention consists of certain improvements in that class of plumbers Vises which are intended for holding sections of pipe together for the formation of a solder-joint, or for holding cocks, couplings, branches, ,elbows, or other fittings in proper position on a pipe, so that they can be united thereto by a solder-joint, the object of my invention being to provide a simple and compact forin of such vise which can be readily adjusted to suit the different classes of work for which it is intended. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which :Figure l is a perspective view of a plumbers vise constructed in accordance with my invention, and Figs. 2, 3, 4 and 5 are diagrams illustrating different uses to which the device may be put.

The implement, in its preferred form, comprises a pair of visesA and B, hung to the opposite ends of a telescopic stem 1), the latter comprising two portions a and a, the portion a being tubular for the reception of the portion a, so that the latter can both turn and slide longitudinally in said portion a of the stem, said portion a being secured in position after adjustment by means of a setscrew d.

The pivot-pin, whereby each vise A B is hung to the end of the stem or shank, is provided with a thumb-nutf, or the pivot-pin may be in the formof athumb-screw, so that each vise can be swung to any desired position around the pivot-pin, and can be secured in position after the desired adjustment has been effected.

Each vise comprises a fixed jaw g and a pivoted jaw g, the latter being hung by a pin 71. to lugson the fixed jaw, and being acted upon by a thumb-nut i, adapted to a screw on, pivoted to the fixed jaw, so that the vise can be readily applied to or removed from the pipes or the different fittings which are to vise-in this case the jaw g'has arounded end 5 for entering the tube of the coupling, the other jaw 9 bearing upon the outside of the same.

In Fig. 4: the vise B is illustrated as hold-- ing in position a branch pipe t, projecting at right angles from the pipe LB, and in Fig. 5 both Vises are shown as-applied to the end portions of pipes a: 0c,which are to be united by a solder-joint, the pipes being shown as supported upon trestles 10.

It will be observed that owing to the facility which is afforded for universal adj ustment of two Vises in respect to each other the device is applicable to all the different classes of work for which such an implement is intended, and it will be observed on reference to the diagrams that the different attachments are so supported that the vise does not interfere in any way with ready access to the joint, so that the application of the solder thereto and the wiping of the joint are not obstructed.

The fixed jaw of the vise A is provided at ard for the stem D of the vise when the latter is being used in a shop; or if the vise is intended wholly for shop use a standard or post may replace the vise A.

Having thus described my invention,l claim and desire to secure by Letters Patent 1. The combination,in a plumbers vise, of the telescopic stem comprising two parts, one free to slide and turn in the other,a vise pivoted so as to be free to swing on the end of said stem, and means for locking the sections of the stem and for locking the vise thereto, substantially as specified.

2. The combination,in a plumbers vise, of

the telescopic standard comprising the two parts, one of which is free to slide and to turn in the other part, with Vises pivoted so as to be free to swing on the opposite ends of the 5 said standard, and means for locking the parts of the standard together and for lockin g the Vises thereto, substantially as specified.

3. The combination of the telescopic standard and Vises hung to the opposite ends of ID the same, one of said Vises havinga jaw with projecting lug serving as a base, whereby the vise can be secured to a bench or table, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of 15 two subscribing witnesses.

JOHN I'IIRST.
